ERTOS-2 is considered a triple-deoxidized filler metal. What additional elements does it contain with silicon and manganese?

ERTOS-2 is classified as a triple-deoxidized filler metal, and its formulation intentionally includes additional alloying elements that enhance its properties, particularly in welding applications. The inclusion of zirconium, titanium, and aluminum plays a critical role in effective deoxidation and improving the mechanical characteristics of the weld metal.

Zirconium serves as a strong deoxidizer, which helps promote the removal of impurities that could affect weld integrity. Titanium, another key component, enhances the strength and fluidity of the weld pool, contributing to better bead appearance and penetration. Aluminum is vital for refining the grain structure of the deposited weld metal, ultimately resulting in improved resistance to cracking and better overall weld quality.

These elements’ combined effects provide not only deoxidation but also contribute to enhanced performance characteristics in the weld, including improved toughness, ductility, and resistance to various forms of degradation. This understanding underscores the significance of each element in achieving the desired weld properties in specific applications.
